3.4 Analog / digital input module
3.4.1 Thermocouple
Use the correct compensating cable between the thermocouple and the terminals – see Table 3.1.
Automatic cold junction compensation (ACJC) is incorporated but an independent cold (reference) junction
may be used.
3.4.2 Resistance thermometer (RTD)
On applications requiring long leads it is preferable to use a 3-lead resistance thermometer.
If 2-lead resistance thermometers are used, each input must be calibrated to take account of the lead
resistance.
Note. Tighten analog / digital input terminal screws to a torque of 0.1 Nm (0.9 lbf.in).
